To all whom it may concern:

Be it known that LORANGE O. OZIAs,of Dayton, in the county ofMontgomery, State of Ohio, have invented certain new and usefulImprovements in Scales; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe letters of reference marked thereon.

This invention relates to an improvement in weighing or weighing andprice scales such as employ a beam and counterweight forcounterbalancing the weight of the goods to be weighed, and has for itsobject to,provide an improved indicating device whereby thesalesman'will be warned or notified just before the desired quantity ofgoods has been placed on the scale, being thereby enabled to weigh outthe exact quantity without the necessity of removing any of the goods,as is now customary. While this is the primary object of the inventionand while the structure illustrated and to' be hereinafter described isdesigned with the above special object in view, invention is applicablein connection with desired to indicate an approximation to thebalancing-point or the failure to remove the entire quantity of goodsfrom the scale after weighing, as is Well understood in the art.

In the accompanying drawings, Figure 1 is a side elevation ofa scalebeam and indicator embodying my present improvements. Fig. 2 is asimilar view of the indicator with the wings or vanes in a differentposition. Figs. 3 and 4: are views of the indicator on an enparts beingin the positions shown in Figs. 1 and 2, respectively.

,Similar letters of reference in the several indicate the same parts.

For the purpose of illustrating my present invention I have adopted atype of scale-beam employed onscales which are commonly known asprice-scales, although it will be understood that the invention iscapable of a universal application to any of the ordinary types ofscales, and hence I do not wish to be limited because ofthe'illustration of a particular type.

it will be understood that the In said drawings the letter A indicates abeam suitably pivoted on a center at B and having a sliding poise O forcounterbalancing the weight of the goods, although it will be understoodthat in lieu of the counterpoise O a pendant D may be employed for thereception of supplemental weights,{or supplemental weights-may beconnected with the beam in any usual or preferred manner forcounterbalancing the weight of the goods being weighed. In proximity tothe beam orin such relation thereto that it may be readily controlled bythe beam is an indicating device,which indicating device consists, generally speaking, of a movable wing or vane which by its movement will.indicate to the salesman that the weight of the goods placed on thescale has nearly reached the balancing limit, or, on the other hand,when the adjustment is properly made will indicate that all of the goodshave not been removed from the scale, but that some remains to be yetremoved. It is desirable to provide an indicator which will give anindication which cannot be misinterpreted and which will be so plain andobvious that it will not be disregarded by the salesman, and for thispurpose it is preferable to employ an indicator which will interpose buta very slight resistance to the movement of the beam and at the sametime will so change the relation of visible parts of the indicator as toexpose or cover as large an area as possible. As a'most convenientmechanism for accomplishing this end I have adopted a double wing orvane arrangement in which very light wings or vanes are employedsuitably mounted on a pivotal center and movable toward and from eachother,

the connection or operative relation with the beam being establishedthrough a short arm or arms, with which the beam or an operating devicecontrolled thereby engages, so as to move the shutters in oppositedirections as the beam moves upor down to either expose the wings orvanes to view or move them so as to conceal them and expose a backgroundor space which is covered by them in theirfirst position. Obviously theposition of the vanes or wings may convey the desired information orserve for the indicating without said vanes being concealed by theirmovement; but the latter arrangement is preferred, inasmuch as itconstitutes a more striking indicator and one not likely to bedisregarded by the sales- 111211.

In the type of scale illustrated to show the application of theinvention a housing E is formed adjacent the outer or free end of thebeam, which housing has pivoted within it a pair of wings, vanes, orshutters F, movable in arcs toward and from each other, so as to closeor open a sight-opening G in the housing, such shutters being preferablyof such shape and so counterbalanced as to require but little power formoving them in eitherdirection, being preferably weighted slightly atthe outer ends, so as to close automatically. The innerends of theshutters are formed or connected with projecting arms I-I, preferablyhaving their upper surfaces rounded and adapted to contact with the flatunder surface of an operating-block I, which latter is connected withthe beam through a stem K, the connection being preferably a pivotal orloose connection at Ya. ed surfaces of the arms is preferably such thatthe shutters will close slowly, the point of contact with the projectionon the beam moving progressively farther from the pivot of the shutteras the shutter'closes and requiring proportionately less and less powerto hold the shutter against closing. In the preferred arrangement theoperating-block I and its stem K are adjusted or weighted to be inbalance with the beam A when the latter is in normal balance without aload being present and with the poise or supplemental weights exertingno influence to put the beam out of balance, while the shutters are soadjusted as to exert a slight upward pushing tendency throughout aportion only of the movement ofthe beam and exerted only before saidshutters are closed or in contact with each other or the stop L, whichnormally arrest-s their closing movement. This power exerted by theshutters or wings, it will be understood, ceases when the block I movesout of contact with the arms H, and from that point on the beam is freeand operates as does the ordinary beam in coming to a balance. The powerexerted by the shutters in this practical embodiment of the inventionillustrated is less than anyload likely to be weighed on the scale andmay operate only throughout, say, the thirty-second of an inch of themovement of the beam in starting from its underbalancing position to itsbalancing position. In operation now when the poise is moved out orcounterweights are applied to the beam to balance a load of the desiredweight the outer end of the beam is moved downwardly and as a result theshutters are separated or moved back within the casing. When the load isapplied to the scale, as said load approaches the limit which will becounterbalanced by the poise or supplemental weights the beam will beginto move, and at the first movement the shutters goods only be put on thescale.

The formation of the roundwill close, thereby indicating to the salesmanthat he has approached a balancing point and must add only a slightquantity in order to bring the scale to a perfect balance.

In the preferred type of indicator the shutters are of a colorcontrasting with the background of the sight-opening. Thus said shuttersmay be black and the background white, and the salesman will know afterhe has set the scale that when the black background appears care must betaken in adding the remaining portion of the load, so that no overloading will occur and the desired weight of This enables him tofacilitate the weighing operation, as it seldom to remove any of thegoods after the same have been put on the scale, as is so often neeessary when weighing with scales where no indicator is employed.

The type of indicator employed by me in accordance with my presentinvention is highly advantageous, inasmuch as it gives a positive andvery marked indication, and by making the area exposed or covered largethe salesmans attention will be invariably arrested without a closeobservation of the movement of the beam itself, as has heret0= fore beennecessary.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- I 1. The combination with a scale-beam,of an indicator embodying a casing having a sight-opening, tendedsurface and movable in said casing from a position in front of saidsight-opening to a position out of line with said opening whereby it maybe concealed by the casing, and operative connections between the wingand scale-beam when the beam is underbal= anced by the weight of theload, whereby the wing is held out of sight and as the beam ap= proachesthe balancing-point, said wing is brought into sight and its connectionwith the beam broken, allowing the beam to reach a balance without beinginfluenced by the wing; substantially as described.

2. In a scale, the combination with a beam mounted on a pivotalcenterwith means for applying counterpoise weight to said beam forcounterbalancing the load, of an indicator embodying a plurality ofsimultaneouslymovable wings or vanes, an operating projection movablewith the beam and cooperating with said Wings or vanes to move themsimultaneously throughout a portion of the movement of the beam wherebya striking visual indication is given; substantially as described.

3. In a scale, the combination with a beam mounted on a pivotal centerwith means for applying counterpoise weight to said beam for balancingthe load, of an indicator embodying oppositely-movable pivoted wings orvanes, an operating projection carried by the beam and cooperating withsaid wings or a pivoted wing having an err-- or never becomes necessaryfor him vanes throughout a portion only of the movement of the beamf ormoving them simultaneously inopposite directions; substantially asdescribed.

4. In a scale, the combination with a beam mounted on a pivotal centerwith means for applying counterpoise weight to said beam to balance theload, of an indicator embodying a fixed casing, oppositely-movable wingsor 10 vanes pivotally mounted in said casing and having oppositely-projecting operating-arms,

of a block connected with the beam and cooperating with saidoperating-arms throughout a portion only of the movement of the beam,and a sight-opening in the casing through which said wings 0r vanes areexposed when the beam isin one position; substantially as described.
